An oil pan for an internal combustion engine has a casing having a first oil chamber and a second oil chamber that are separated from one another. A valve connects the first and second chambers with one another in an open position of the valve. The valve is switched temperature dependent, wherein the valve is closed at a temperature below a switching temperature. An outlet opening communicates with the first oil chamber. The first oil chamber has a first oil volume and the second oil chamber has a second oil volume, wherein the first oil volume is smaller than the second oil volume. The outlet opening is positioned in an exterior wall of the first oil chamber and provides a connecting opening for connecting an oil cooler to be connected to an exterior wall of the casing.
